Just after Minnesotans enjoyed the warmest temperatures they’ve felt all year, a snowstorm is expected to dump up to 10 inches of snow Thursday in some counties, making travel hazardous for the afternoon commute and evening hours.

The State Patrol is investigating a serious crash at 35W and County Road 10 Thursday afternoon.

The ramp to northbound 35W and County Road 10 was closed in Mounds View, creating a backup of more than five miles after a rollover accident ejected a 17-year-old from St. Paul. The condition of the teenager isn’t known.
